Alexandrite
For many years, alexandrite was almost impossible to find because there was so little available. Russia still produces a few gemstones and now the best quality comes from Sri Lanka.
In 1987, a new find of alexandrite was made in Brazil at a locality called Hematita. The Hematita alexandrite shows an attractive color change from raspberry red to bluish green.
In 1995 a new source of fine alexandrite was found in Southern Tanzania.
South Madagascar also produces now fine specimens.
